    • Apparatus and procedure for elimination of water, air and other gases from their mixture with SF6 gas, where apparatus (A) for slowed down separation of cited ingredients contains thermo-isolated housing (1) whose inside space (3) is filled with cooling substance (3a) in which metal vessel (2) is immerged with the adsorbent that is constructed with connecting tube (5) and connector (6) for connection in operation on the vessel (7) which is some shielded high voltage plant, tank or some other high voltage device containing SF6 gas under over-pressure that has to be purified. The invention also relates to the apparatus (B) for accelerated separation of ingredients, of the same construction as the apparatus (A) only with double connection of the vessel (12) with tubes (15, 15a) and connectors (16, 16a) for connection in operation to the vessel (17), while in the tube (15a) in the feed back circuit is connected the pump (19) with filter (18) for acceleration of the circulation of purified gas SF6. Invention contains the procedure that is performed in the apparatus (A and B), when conduction of SF6 gas in a mixture with other ingredients over the adsorbent, cooled to the temperature over -15 DEG C is done.

    • Recovery of re-useable grade sulphur hexafluoride from a contaminated source comprises first evacuating a stream of contaminated sulphur hexafluoride from a transport or storage vessel (10) into a separation via an intermediary and optional clean-up stage, involving scrubbing and filtering. Sulphur hexafluoride in the partially clean-up stream is directly solidified within the separation vessel (30), preferably onto a large surface area tube heat exchanger (4) arranged within the separation vessel (30). Uncondensed contaminant gases are vented to atmosphere, and the solidified sulphur hexafluoride within the separator vessel is melted and transferred to a collection vessel (5) for subsequent reuse. The recovery process re-introduces sulphur hexafluoride obtained from the collection vessel (50) back into the separation vessel (30) for effecting heat transfer to the solidified sulphur hexafluoride thereby to assist in said melting. A valve assembly (53) is provided between the collection vessel (50) and separator vessel (30), which is controlled to allow warm, substantially uncontaminated and previously cleaned sulphur hexafluoride gas to be transferred from the collection vessel (50) to the separator vessel (30) to melt the solidified sulphur hexafluoride. The valve assembly (53) allows the melted sulphur hexafluoride to be transferred to the collection vessel (50) in liquid or gas phase.
    • 从污染源回收可再利用级六硫化硫包括先将污染的六氟化硫流从运输或储存容器(10)排出到通过中间和任选的清理阶段进行分离,包括洗涤和过滤。 部分净化物流中的六氟化硫在分离容器(30)内直接固化,优选在布置在分离容器(30)内的大表面积管热交换器(4)上固化。 将未冷凝的污染气体排放到大气中,并且分离器容器内的固化的六氟化硫被熔化并转移到收集容器(5)中以供后续再利用。 回收过程将从收集容器(50)获得的六氟化硫重新引入分离容器(30)中,以进行固化的六氟化硫的热传递,从而有助于所述熔融。 阀组件(53)设置在收集容器(50)和分离器容器(30)之间,其被控制以允许温暖,基本上未被污染并预先清洁的六氟化硫气体从收集容器(50)转移到分离器 容器(30)熔化固化的六氟化硫。 阀组件(53)允许熔融的六氟化硫以液相或气相转移到收集容器(50)。
